- Objectives: Perform multi-organ expression profiling to identify gene markers predicting postoperative complications and hospitalization after coronary artery by-pass grafting (CABG) surgery. Background: Identifying patients who are at increased risk of morbidity and prolonged post-operative stay is of interest from both health-economic and individual patient perspectives. Patients with diabetes often present with inflammatory conditions and have prolonged hospitalization after CABG. The recent development of technologies to generate high-dimensional data provides an opportunity to identify preoperative markers that can be used to help optimize preoperative planning to minimize postoperative complications. Methods: We analyzed 198 whole-genome expression profiles of liver, skeletal muscle, and visceral fat isolated from 66 patients undergoing CABG in the Stockholm Atherosclerosis Gene Expression (STAGE) study. The findings were validated in pre-operative blood samples isolated from 181 patients undergoing CABG at Tartu University Hospital. Results: As shown in other studies, diabetic CABG patients in the STAGE cohort also had prolonged hospitalization time (P<0.02). Out of ~50 000 mRNAs measures in the liver, skeletal muscle and visceral fat in 66 STAGE patients, the mRNA levels of anti-inflammatory gene dual specificity phosphatase-1 (DUSP1) correlated independently with post-operative rehabilitation and separated the patients into those with normal (8 days) and prolonged hospitalization (>8 days). In the validation cohort, preoperative blood levels of DUSP1 separated patients with short and long hospitalization stay (P=9x10-10). Conclusions: From genome scans in three separate organs, we identified the anti-inflammatory gene DUSP1 as a pre-operative marker indicating risk for prolonged postoperative stay after CABG.
